Hazard was late returning back from a visit to watch his former club Lille in action against Monaco on Sunday, and he lost his place in the side that beat the Bundesliga outfit because of the mistake.

Torres will definitely miss the game against the Baggies, and the Spain international will not return until after the upcoming international break.

The Portuguese boss said: "[Torres] is injured but he is doing well, he is recovering well. We think, if things go to plan, he will be back after the international break."

The former Liverpool striker's absence means Mourinho is likely to continue with Samuel Eto'o up front after he scored twice in the win over Schalke, although Demba Ba staked his claim with a goal from the substitutes' bench.

Mourinho has Ryan Bertrand available for selection, while Marco van Ginkel is a long-term absentee.
